Doug's headers not fitting - frustration

I've been down this road before with ill fitting headers and swore I'd never do it again.

I went with TTI shorties and eliminated all the ill fitting bullshit for good.
If only I would've known. I bought Doug's because of the glowing reviews of how they bolted right up out of the box, but no one expects the Spanish Inquisition.

I can't help thinking there's something I'm overlooking, but I kind of ran out of ideas after moving it all the way to the passenger side today and still having a problem. I can keep screwing around, or I can get it over with. Same mindset I had when I dented them for the torsion bars.

I've got a set of Schumacher BB headers that are shorty design. Those things are the bee's knees. I bought them for this car when it had a 400 in it. I will probably put them on my road runner when it goes back together instead of the long tube Hooker 2-piece headers that I was running on it.
